It addition, coldplate 30 is formed as flat tubular by the plate of the plate bent or overlap.Specifically, undertaken sheet material bending or overlap to form the stream that cooling current are logical, and constitute coldplate.Accordingly, in the structure of water-cooled heat exchanger, cooling water flows in the stream of coldplate, and needs the air-breathing carrying out cooling down to flow in the air-breathing stream outside coldplate, so that the two carries out heat exchange.
As it is shown in figure 5, the upside pipeline board 21 of core 50 is connected to the pipe arrangement 51 of cooling water turnover.It addition, the peristome at pipeline board 20 is provided with the riveted plating 10 being brazed together with pipeline board 20, the suction line that peristome is come in and gone out with the confession air towards outside of water-cooled heat exchanger by riveted plating 10 is connected.
Fig. 7 is the partial enlarged drawing of the riveted plating state during soldering riveted plating of water-cooled heat exchanger of the present utility model.As shown in Figure 7, in the water-cooled heat exchanger of above-mentioned such flaggy stack structure, the pipeline board 22 of downside is inserted into inside riveted plating 10, when pipeline board 22 and riveted plating 10 are carried out soldering, in order to ensure riveted plating and pipeline board close contact, as arrow A shows, fixture is utilized to press from outside to riveted plating 10, but, in pressing not at that time, the intilted situation of the such riveted plating of arrow B 10 can be produced.For this, on the one hand, need to make riveted plating stably contact with pipeline board, it is to avoid C place produces gap；It is necessary to ensure that the flatness of riveted plating on the other hand.
Fig. 8 is the partial enlarged drawing of the fastening state of the first pawl on the riveted plating of water-cooled heat exchanger of the present utility model.
As shown in Figure 8, riveted plating 10 stretches out the first pawl to pipeline board 20 (downside pipeline board 22), first pawl is pressed into pipeline board 20 and rivets with the edge of this pipeline board 20, accordingly, first passed through before riveted plating 10 and pipeline board 20 are carried out soldering and the first pawl is pressed into pipeline board 20, make close contact (contiguity) between riveted plating 10 and pipeline board 20, realization pre-fixes, thus when soldering, ensure that reliable contacts between riveted plating and pipeline board, avoid the formation of gap, and then make soldering stably carry out.
In fig. 8, the first pawl is respectively provided at long side and the short brink of riveted plating 10, including the pawl 12 of the pawl 11 of long side of riveted plating 10 and the short brink of riveted plating 10.Certainly, the first pawl can also only be located at long side or the short brink of riveted plating, namely only includes the pawl 11 of the long side of riveted plating 10 or the pawl 12 of the short brink of riveted plating 10.
Fig. 9 is the partial enlarged drawing of the fastening state of the second pawl on the pipeline board of water-cooled heat exchanger of the present utility model.Figure 10 is the partial enlarged drawing of the second pawl on the pipeline board of water-cooled heat exchanger of the present utility model.
As shown in Figure 9, Figure 10, pipeline board 20 (downside pipeline board 22) projects upwards with approximate 90 degree with guaranteeing perpendicularity and is formed with the second pawl 23, riveted plating 10 is formed the pawl support 13 accepting the second pawl 23 along the bearing of trend of the second pawl, pawl support 13 is formed as being coated with the structure of the second pawl 23 from both sides, so, second pawl 23 is pressed in pawl support 13, and makes riveted plating 10 and pipeline board 22 be in close contact.
According to said structure, before riveted plating and pipeline board are carried out soldering, it is pressed into by the second pawl and riveted plating is further secured on pipeline board by pawl support, thus when soldering, ensure that reliable contacts between riveted plating and pipeline board, it is prevented that riveted plating tilts, it is ensured that its flatness.
Additionally, in the above-described embodiment, formed so that substantially vertical state is prominent from pipeline board at the second pawl, pawl support is formed as being coated with the structure of the second pawl from both sides, but, as long as the snap-in structure forming the second pawl and pawl support makes riveted plating and pipeline board reliable contacts, this utility model is not limited to the form of above-mentioned pawl.For example, it is also possible to make that the second pawl is located at riveted plating and pawl support is located on pipeline board.
It addition, in the above-described embodiment, being illustrated for water-cooled heat exchanger, the heat exchanger of other cooling mediums is equally applicable.
Additionally, in the above-described embodiment, mention " on ", D score, the direction relations such as "left", "right" limit and be intended merely to facilitate explanation and adopt, the position not refered in particular in heat exchanger of the present utility model between each parts is limited only to above-mentioned qualified relation.
As mentioned above, this utility model with reference to accompanying drawing to preferred embodiment having carried out abundant record, but will appreciate that various deformation or change to those skilled in the art, these deformation or change, as long as no departing from the scope that the technical solution of the utility model limits, all should be included in wherein.
